Specification of Letters Patent.

Application filed December 19, 1911. Serial No. 666,660. 1

To all whom it may concern: v,

Be it known that I, BRUNO voN BtiLrziNosLownN, a citizen of the United States of America, residing in New York, in the borough of the Bronx, county and State of New York, have invented certain new and useful Improvements in Machines. for Bending the Cross-Heads and Eyes of Wire Bale- Ties, of which the following is a specification.

This invention relates to machines for bending the crossheads and eyes of wire bale-ties and more especially to improve,

ments in the machine for which Letters Patent were granted to me on May 17, 190 1,

No. 760,100, whereby the construction of the machine is considerably simplified, the number of parts required for the same greatly reduced, and the repairing of the same facilitated as compared with the prior ma chine made under the Letters Patentrethe patent referred to that the p0wer-shift-' ing mechanism described and claimed there.- in was too delicate and complicated and liable to breakage and repairs, which owing to the complexity of the construction could not be done by simply replacing the broken parts but by returning the machine to the factory. This discredited the machine and discouraged its use. Furthermore, the complicated power-shifting mechanism was liable to give out after a comparatively short use of the machine, especially when the ma chine was subjected to severe strain for making the guaranteed production of 25,000 bale-ties in a working day of ten hours. To

overcome these objections and deficiencies referred to, the machlne forming the sub-' tion of the machine on line 33, Fig. 1

The improved machine, in its general con-; struction, is built on the same lines as the prior machine, shown in Patent No. 7 60,100 before referred to. It consists mainly of a; power-shifting mechanism, which is ar-'; ranged between the crosshead and eye-bending devices and the shafts of the same, which shafts are arranged sidewise of and parallel; with each other, while the shank-twisting and motion-transmitting mechanisms are shown at the right-hand end of the machine and the wire-clamping and ejecting devicesare arranged at the left-hand end of the ma-i chine, in front of the die-heads, carrying the} crosshead and eye-bending devices. In place? of a treadle-mechanism for start-ing the machine, a hand-operated lever is arranged ati one side of the machine for starting or stop-; ping the machine. I -As the power-shifting mechanism forms .the essential feature of the present machine,

and one to which the simplified construction? of the machine is due, it will be first de} scribed, after which the crosshead and eye-5 bending, wire-clamping, shank-twisting, moi tion-transmitting and ejecting devices Willi The p0wer-shifting mechanism.The power-shifting mechamsm 18 shown in de-,

tail in Figs. 6 to 9, and 13 to 15. It is 10-5 cated between the shafts C and C, which; carry at their front-ends respectively the; die-heads with the crosshead and eye-bend-i ing devices. It is supported between a lower transverse bridge-plate A, which connects the supporting side-standards A, A of the frame A, and an upper bridge or cap-plate A between which and the lower bridge A a space is formed, for guiding a vertical, rcciprocating slide-plate Q in ways of the lower and upper bridge-plates in line with the central vertical longitudinal plane of the machine and parallel with the axes of the shafts of the crosshcad and eye-bending devices. Reciprocating motion is imparted to the vertical slide-plate Q by means of two cranks 9, Q2, which are mounted at an angle of 90" to each other on an auxiliary shaft. S that receives rotary motion from an intermediate shaft S by bevel gear wheels 0, 0. The shaft S is supported transversely to the longitudinal axis of the machine in bearings of the lower bridge plate A. The auxiliary shaft 5 passes through a horizontal slot (1 in the slide-plate Q. The cranks Q2 are provided at their ends with anti-friction rollers which engage cam-pieces 9", 9, that are attached to opposite sides and at diagonally-opposite points of the vertical slide-plate Q, the crank g and campiece 9 producing the forward motion and the crank Q2 and canipiece Q6 the return-motion of the slide-plate. The cam-pieces Q5, 7, are attached by means of screws to the slideplate Q and provided with slightly-inclined faces having straight upper and lower ends for taking up the action of the anti-friction rollers at the ends ofthe cranks. Integrally with the hub of the crank q is made a sen'ii-circular lockingcam Q7, the inner straight edge of which is in line with the center-line of the crank q and which is recessed at one end so as to extend around the anti-friction roller of the crank g, and rounded off at the opposite end, as shown in Fig. 6. In place of making the locking-cam {[7 in one piece with the/hub of the crank 9, it may be made in. a separate piece and attached by screws or otherwise thereto. The object of the locking-cam is to hold the vertical slide-plate Q rigidly in position after it has been moved by the crank 9' into its extreme forward position, as shown in dotted lines in Fig. (3, in which position it acts on the face of the straight lower portion of the upper can'i-piece of the slide-plate and is held in contact therewith while the crank Q2 and locking-cam continue their rotary motion for such a length of time until the work of the crosshead and eye-bending, wire-clamping, shank- 1 twisting and ejecting devices is completed.

lVhen the second crank g has moved through an angle of 270, it acts on the lower cam-piece Q6 at the opposite side of the slide-plate Q and returns, by completing its rotation, the slide-plate into its former initial 01 starting position, as shown in full lines in Fig. 6. The alternating motion of the cams 9 produces the reciprocating motion of the slide-plate whilethe locked position of the same in its forward position is produced by the semi-circular locking-cam.

The vertical reciprocating slide-plate Q forms the motion-transmitting organ by which the operative parts of the machine are placed in their different working positions. It performs a four-fold function: firstly, of oscillating the shifting lever L of the power-shifting mechanism from one side to the other by means of a suitable intermediary mechanism; secondly, of supporting the laterally-shiftable heads L for operating the sliding sleeves on the shafts of the crosshead and eye-bending devices; thirdly, of shifting a clutch-device by means of which rotary motion is imparted to the shafts of the crosshead and eye-bending devices, into mesh with the motion-transi'nitting gears; and fourthly, of producing the withdrawal of the locking-bolt from the main driving gearwheel of the motiontransmitting mechanism during its forward motion and the relocking of the main gearwheel during the return-motion of the slideplate and after the twisting of the shanks of the crossheads or eyes is completed.

The primary function of the reciprocating slide-plate Q, namely, the oscillation of the shifting lever L, is accomplished by a mechanism interposed between the upper rearcorner of the slide-plate and the rear-end of the lever L. The lever L is fulcrumed to a raised seat on the central portion of the capplate A and extended at both ends beyond the cap-plate. The rear-end of the lever L is acted upon by the oscillating mechanism, which consists of a rack-bar Z, attached to the upper rear-corner of the slide-plate Q, and a cam-shaft Z, supported in neckbearings of an extension-plate L. The rack-bar Z intermeshes with a loose pinion Z on the cam-shaft Z and imparts intermittent rotary motion thereto by the forward, and return-motion of the rack-bar Z. The camshaft Z carries at its upper end a cam Z having a semi-circular face-recess in its upper part, as shown clearly in Figs. 13, 14 and 15. A disk Z on the shaft Z, adjacent to the pinion Z carries a spring-actuated checkpawl Z which engages either one of two tary motion imparted to the pinion Z by the 1 rack-bar Z to the cam-shaft Z and the rebeing provided with hooks Z which are connected by a helical spring Z that ex- "tends over the rear-end of the shifting lever so that the pivoted elbow-levers can act alternately on the shifting-lever and oscillate thereby the same from one side to the other of the longitudinal axis of the machine. The oscillating motion of the shifting-lever L from one side to the other is so timed by the reciprocating motion of the slide-plate and the motion of the rack-bar and pinion by which the recessed locking-cam is turned that the pivoted elbow-levers are placed either into the position shown in full lines in Fig. 18, or into their shifted position, which like the shifting-lever is shown in dotted lines in the same figure. At the end of the semi-circular turning motion of the camshaft, the cam Z is locked by a springactuated check-pawl Z which engages one of two diametrically-opposite notches in the lower part of the cam Z as shown in Fig. 13. On the extension-plate L, but in front of the fulcrum of the shifting lever L, are located stationary checks Z which are provided with inclined-faces that act as stops for holding the front-end of the shiftingleverL in its proper position while the rearend of the same is held in locked position by the face of the recessed locking-cam Z. he front-end of the shifting-lever L is forkshaped, the fork-shaped end serving for front-corner of the slide-plate, as shown clearly in Figs. 6, 7 and 14.

To the upper front end of the cap-plate A is attached a forwardly-projecting centerplate L" which is located below the forked front-end of the shifting-lever L and provided with parallel guide-slots Z", equal in length with the forward motion or stroke, imparted to the reciprocating slide-plate Q. so that the upright shifting-finger Z can move with the laterally-shifting slideheads L? and the sliding-sleeves B or B on the shafts C, C in forward direction. The re cess in the forked front-end of the shifting lever L is made V-shaped, the sides of the V-shaped recess being arranged in such a manner that when one side is in line with the inner edge of one of said guide-slots, the shifting-lever is in one position while when the other side of the V-shaped recess is in line with the inner edge of the other guide slot, the shifting-lever is placed in its second or shifted position, as shown in Fig. 1, and respectively in full lines and dotted lines in Fig. 13.

The laterally-shifting slide-heads L engage either one or the other of the sliding sleeves B or B on the shafts G, C of the crosshead or eye-bending devices and shifts them alternately into forward or backward position on the shafts C, C by the reciproeating motion of the slide-plate Q. The opposite end of the laterally-shifting slideheads L moves clear of the sliding-sleeve on the opposite shaft so as not to move the same while the bending devices on the first shaft are actuated by the shifting slide-piece on the same for bending either the crosshead or the eye at the ends of the wire-blanks fed;

into the machine.

The lower front-end of the reciprocating slide-plate Q is provided with a forwardly and downwardly-extending hanger-portion g which is separated by a recess 9 from its. '25 main-portion. The lower part of the hangerportion 9 forms a bearing for the front-end of a longitudinally-sliding center-shaft S which is supported by and turning freely in a second hollow shaft S that is supported in suitable journal-bearings at the underside of the lower bridge-plate A of the machine frame. A collar f at the front-end as well as a collar f attached to the rear-end of the longitudinally-sliding center-shaft S holds the same in proper position in the hollow shaft S and limits its motion in the bearings of the lower bridge-plate A. To the read-end of the shaft S is keyed a movable clutch-member f which, when the slide-plate Q arrives at the end of its forward motion, is placed into mesh with a fixed clutch-member f on a sprocket-wheel 10 that is mounted loosely on the hollow shaft S so as to impart rotary motion by a sprocket-wheel and chain transmission to the shaft S and the shank-tw1st1ng mechanism connected there-' with. Rotary motion is imparted to the sprocket-wheel 10 by a sprocket-chain transmission from an intermediate shaft S which is driven by a gearwheel transmission from the main driving-shaft S to which rotary motion is imparted by a belt and pulley-transmission from an overhead shaft or an electric -motor, as desired. A main gear-wheel m is one full rotation of the main gearwheel on three twists are formed on the shank of the crosshead, while for one full rotation of the main gearwheel m the gearwheels f", f impart four rotations to and form four twists to the shank of the eye of the bale-wire. The front-end of the longitudinally-shifting shaft S is provided in the lower recessed portion of the reciprocating slide-plate Q with a disk f which is keyed to the shaft S, said disk engaging during the forward motion a collar f on a horizontally-guided locking-bolt i that is located sidewise of and parallel with the shifting-shaft S and guided in the bearings below the lower bridge-plate, the middle portion of the locking-bolt f being provided with a fixed collar f and a helical spring f between said collar and the left-hand bearing, While its rear-end projects beyond the right-hand bearing on the lower bridge-plate and is slightly tapered so as to be adapted to e11- gage a socket-hole f in the web of the main driving gearwheel m as soon as the twisting of the shank of the crosshead or of the eye of the bale-tie is completed. The rearward motion of the locking-bolt f into locking engagement with the socket-hole f of the main gearwheel m is accomplished as soon as one full rotation of the main gearwheel is completed, in which case a spring-latch f mounted on the disk f is placed in line with a segmental recess f? on the circumference of the disk so that the latch is permitted to give under the pressure of the collar at the front-end of the locking-bolt f and cause the latter to clear the recess of the disk and move under the action of its helical spring f instantly into the socket-hole of the main gearwheel so as to lock it rigidly in position during the time when the rotary motion of the main gearwheel for producing the twisting of the shanks of the crossheads or eyes is not required.

The mosslzcacl bending dem'ces.The crosshead made by the bending devices is shown in Fig. 31, and the crosshead bending devices themselves in Figs. 25 to 28. They are operated by a sliding-sleeve B located on the horizontal shaft C of the crossheadbending devices, alternately with the eyebending devices which are operated by a sliding-sleeve B on the shaft C. The shafts C, C are arranged sidewise of and parallel with each other and supported in bearings of upright standards A and A which are attached to the supporting-frame of the machine. The sliding-sleeves B and' B are engaged alternately by the transverse slide-heads L which are reciprocated by the vertical slide-plate Q and alternately shifted from one side to the other by the shiftinglever L. The sliding-sleeves B, B are connected with the shafts C, C by transverse keys 6 which are guided in slots 12 of the shafts. The sleeves B, B are provided with flanges at opposite ends, the front-flanges being provided with ears 5 which by means of intermediate link-connections serve for operating the primary and h0ok-bending levers of the crosshead or eye-bending devices. To the ends of the shaft C, G are applied die-heads E, E on which the operating parts of the crosshead and eye-bending devices are mounted. The die-head E of the crossheadbending devices is formed of an L-shaped forwardly-projecting plate which carries at one side the primary bending-lever E which is bent at an obtuse angle so as to correspond with the angle formed by the forward end of the crosshead toward the wire-blank e to be bent, said lever being attached to an arm (2 of a pivot e that is journaled in the diehead E, as shown in Figs. 25 and 26. A fixed bending pin 6 projects centrally from the end of the pivot 6 while a pinion 6 that is engaged by a gearwheel e, is keyed to the opposite end of the pivot e and located like the gearwheel e 011 the opposite side of the die-head E. The gearwheel e is mounted on a pivot of the die-head E and rotated by the forward motion of the sliding-sleeve B through the medium of a pivotlink b which is connected with the ear 6 on the front-flange of the sleeve B and by a front-shoulder b with a crank-pin b on the gearwheel e. The pivot-link b is guided by means of a longitudinal slot 6 on a fixed pin 6 of the die-head. The motion imparted by the front-shoulder b of the pivot-link b imparts the required rotary motion to the gearwheel 6 for swinging by means of the intermeshing pinion e the primary bending-lever E and thereby the end of the wire-blank around the projecting 'bendi11 3in a and backwardl over the wire-blank, as shown clearly in dotted lines in Fig. 25, the obtusely-shaped bendinglever E producing at the same time the obtuse angle at the front-part of the crosshead.

A second or hook-bending lever F is fulcrumed to a pivot 7 onthe lower front-part of the die-head E and provided with a hookshaped projection F by which the wireblank 2 is bent around a second stationary bending pin f of the die-head, which pin is located in front of the pin 6* so as to form the hook-portion of the crosshead. A camsurface f on the upper edge of the hookbending lever F serves for pressing an intermediate spring-actuated bendinglever F, which is pivoted to the die-head E, against the hook-shaped end of the wire-blank, said lever F being located between the lower part of the primary bending lever E and the hook-bending lever F, as shown clearly in Figs. 25 and 27, so as to bend the portion of the wire-blank inwardly between the bending pins 6 and f. The rear-611d of the primary bending-lever F is provided with bent-over lugs e by which the wireblank 2 together with the bent-over portion is held in proper position for the wirec-lamping mechanism, which will be described later on. The hook-bending lever F is operated by a pivot-link f which connects its lower rear-end with a second ear 6* at the lower part of the front-flange of the sliding-sleeve B. A cheek 6 on the arm 0 of the lever E serves for holding the bent-over end of the'wire-blank at one side while an oblong cheek 6 located sidewise of the hook-bending lever F holds the crosshead formed by the bending levers on the other side. A laterally-projecting latch 6 guided at the forward end of the die-head is beveled downwardly and acted upon by a flat spring 0 attached to the opposite side of the die-head, as shown in FigsJ27 and 26. The latch 6 prevents the upward motion of the shank of the cross-head just formed and gives under the pressure of the pr'- mary-bending lever E as it swings over with the bent-over wire in forming the crosshead. The keepers e and a hold the middle portion of the crosshead in position on the bending-pins e and f" and keep the cross-head in place in a plane parallel with the die-head, as shown in Fig. 27. The joint operation of the primary bending-lever E, the fulcrumed hook bending-lever F, the in- =termediate bending-lever F and the cheeks e and e", produce in connection with the hook bending-pins, the formation of the crosshead, shown in Fig. 31. On the diehead E is further arranged above the end of the hook bending-lever F a pusher e which passes through a hole in the die-head E and which is held in position by the tension of a helical spring 6 at the opposite side of the same. The pusher e is attached to a plate 6 which is provided with a guidepin 6 and cushioned by a second helical spring 6 as shown in Figs. 29 and 30. On the head of the guide-pin e is placed a wire-spring e which acts on a latch 6 that is pivoted to ears on the guide-plate e and projected into thepath of a lug b on the sliding pivot-link b? so that the lug b is permitted to pass beyond the pivoted latch during its forward motion but actuates the same during its return-motion so that the pusher is moved laterally against the completed crosshead while the cross head bending-devices are returned from their bending position into their initial or starting position, the pusher pressing the crosshead sidewise and releasing it from the bending-pins ready for the action of the ejecting-devices. The crosshead bendingdevices are fully described and claimed in the prior patent referred to and not claimed in this application.

The eye-bending de'vicee 'lhe eye-bendthe shank of the crosshead or eye.

ing devices are shown in Figs. 32 to 35. They are supported at the front-end of the shaft C and consist of an- L-shaped supporting die-head E an eye-bending lever F that is attached to a pivot b on the head E similar to the primary bending-lever E of the crosshead-bending devices, and intermediate motion-transmitting mechanism for the lever F consisting of a gearwheel Z1 and pinion I), which are actuated by an intermediate link-connection 6 between an ear I) on the sliding-sleeve B and the crank-pin I) on the gearwheel I). The link 5 is provided at its front-end with a lug 5 which engages on the returnmotion of the link 6 the crank-pin b and returns the gearwheel 6 pinion b and bending lever F into their initial positions. The eye-bending lever F is provided with a keeper Z) that projects over the wireblank and holds it in position while its end is bent back around a projecting bendingpin 6 on the pivot Z) of the bending-lever F and past a bending pin 5, as shown in Fig. 33. The die-head E is provided at its front-end, in line with the upper edge of the bending-lever F with an ingoing cheek b which is rounded off toward its front-end and which serves for the easy insertion of the wire-blank 2 and as a proper support for the same during the bending operation. When the end of the wire-blank a has been bent around the bending-pin I), as shown in dotted lines in Fig. 33, the bent-over wire thus formed is taken hold of by the wire-clamping devices, which are in line with the eye-bending devices. In front of the wire-clamping and ejecting-devices are supported on the retaining guide-strips of the ejecting-devices V-shaped guides cl which are made of sheet-metal and provided with U-shaped lower parts, as shown clearly in Figs. 1 and 16, and which serve for guiding the wire-blanks when they are inserted toward the slotted eyes of the ejectingdevices adjacent thereto and inwardly over the bending-levers until they abut against the angular portions of the die-heads, as shown in dotted lines in Figs. 25 and 27 for the crosshead, and in Figs. 83 and 34 for the eye of the bale-wire. By the V-shaped guides, the wire-blanks are conveniently and reliably guided into their proper position in the die-heads until arrested by their rearends, so as to be acted on by the bending, wire-clamping, shank-twisting and ejectingdevices.

The wire-clamping dem'ces.When the crosshead or eye-bending operation is completed, the wire-blank and theoverlapping' bent-over end of the same are firmly gripped by aclamping-device preparatory to the twisting operation, that is to be imparted to The clamping devices are located on the inner jside of the front-standard A in line with the. crosshead and eye-bending devices, and -COI1SlSl3 each of a stationary clampmg cheek g and an elbow-shaped movable clampingcheek g fulcrumed to the standard A, as shown in detail in Figs. 17 and 24. The upper end of the standard A is recessed at each corner for receiving the stationary cheek g, which forms, in connection with the correspondingly-recessed cheek g a rigid support for the shank of the crosshead or eye. The upper end of the movable clamping-cheek g is connected by a helical spring 9 with a center-pin g on the supporting standard A, so as to hold the cheek normally away from thestationary cheek and. against a stop-pin g on the standard A. Oscillating motion is imparted at the proper time to the movable clamping cheek g by the beveled face of an upright cam g attached to a horizontally-reciprocating slidepiece g., which is actuated by the shiftingsleeve B or B on the shaft O or O engaging an upright arm at the rear-end of the slide-piece g, as shown in Fig. 2 and in detail in Figs. 20 and 21. The slide-piece is guided in a stationary guide-box and moved forward through an opening in the standard A, the clamping-cheeks g,

eye firmly until the shank-twisting operation is completed when the slide-pieco (1 and upright arm (7 are returned by the sleeve B or B to their in tial or starting position and the movable clamping-cheek g by the spring 9 to its stop-pin (7 The s/umlatwisting mechaaism.'lhe twisting of the shanks of the crossheads or eyes is accomplished by the following mechanism: On the main-shaft S is mounted a pulley P, which receives continuous rotary motion by a belt from a suitable power-shaft and transmits the rotary motion by a pinion and gear wheel g 9 to an intermediate shaft S and from the latter by a sprocketwheel w and a sprocket-chain 10 to a loose sprocket-wheel 10 on the hollow shaft S, which latter is supported in bearings at the underside of the table A below the vertical slide-plate Q, as shown in Figs. 1 and 3. On the shaft S is mounted, adjacent to the sprocket-wheel 10 the main bevel gearwheel m. The sprocket-wheel ta is thrown into mesh with the shaft S by the movable clutch-member f on the rear-end of the shaft S shown in F ig. 3. The clutch-member f is moved forward with the shaft S by the forward-motion of the slide-plate Q and engages, as soon as the crosshead or eye-bending and clamping devices have accomplished their functions, the clutchmember f on the sprocket-wheel 10 so as to rotate the shaft S hollow-shaft S and the main gearwheel m. Simultaneously with the intermeshing of the clutch-members F, f*, the locking-bolt f of the main-gearwheel m, is withdrawn by the action of the disk f on the collar f at the front-end of the shiftable locking-bolt so that the main gear-wheel m is free to rotate. The main gear-wheel m intermeshes at one side with the intermediate gearwheel f and the latter with a gearwheel f of equal size on the shaft C of the cross-head bending devices, and on the other side with a gearwheel f" and the latter with a gearwheel f of equal size on the shaft of the eye-bending devices. Alongside of the gearwheels f and f on the shafts C, C are arranged disks w, w which are notched at one point of their circumference and engaged by check-pawls w, 0.0 which prevent the rotation of the shafts C, G in a direction opposite to that required for the twisting motion of the shanks of the crossheads and eyes. The gearwheels f and f are splined to the rear-ends of the shafts C, C, during the shank-twistingop eration by the shifting of interior shafts G G which carry the splines C at their rearends. The motiontransmitting sprocketwheels and chain are kept continuously in motion as long as the pulley P is driven from the source of power, the sprocket and chain transmission forming with the main gearwheel m and gearwheels f", f and f, the means for transmitting rotary motion to the shafts G, C at the time when the twisting of the shanks of the crossheads oreyes is to be performed. The ratio between the teeth of the main gearwheel m and the teeth of the gearwheels f, f is 3 to 1, so that for each rotation of the main gearwheel three rotations are imparted to the gearwheels f", f and three rotations to the shaft C. 0n the other hand, the ratio between the teeth of the main gearwheel m and the teeth of the gearwheels f*, f is 4 to 1, so that for each rotation of the main gearwheel m four rotations are imparted to the gearwheels f", f and thereby four rotations to the shaft G. The motion -transmitting mechanisms for the shank-twisting mechanisms are called into operation by the reciprocating slide plate Q; on the one hand, and the shifting motion of the sliding-sleeves B, B and the spline-connections of the shafts C, C with the driving gearwheels f and f on the other hand. so as to produce either three rotations of the shaft C or four rotations of the shaft C and the corresponding number of twists on the shanks of the crosshead or eye just.

T720 ejecting deocea-The ejecting devices are shown in Figs. 16 to 19. They are located on the front-side of the upright front-standard A? adjacent to the clampingdevices on the rear-side of the same. They consist. of oscillating-levers t which are formed of lower portions or arms 6. that are fulcrumed at their lower ends at t to the upright standard A and of angular and outwardly-bent upper portions or arms 6 The lower arm of each ejector is provided with parallel ribs 25 and with a hinged and spring-actuated latch i that projects over and beyond the inner edge of the lower ejector-arm, and that is provided with a nose t at the inner lower end so as to be engaged by a cam g on the horizontallyrcciprocating slide-piece g of the wireclamping device which cam is passed through the opening 9 of the standard A The. front-edge of the cam g on the reciprocating slide-piece g is straight, and the rear-edge inclined in downward direction, asshow'n in Figs 20 and 21. The frontedge of the cam 9 of each slide-piece g engages the hinged and spring-actuated latch t on the ejector-arm 25, when moved in forward direction so as to swing the latch forward against the tension of its spring into the position shown in dotted lines'in- Fig. 23. Adjacent to the cam g is arranged on the slide-piece g a shoulder 25, which acts on the return-motion of the slide-piece on the latch i and raises it with the ejector so as to swing it with the same into the intermediate position shown in dotted lines in Fig. 18, and produce the slipping out of the shank of the crosshead or eye from the slotted eye 25 'of the ejector. By the continuation of the return motion of the slidepiece 9, the inclined rear-portion of the cam g engages the latch i and swings it with the ejector-arm quickly in lateral direction into the second position, shown in dotted lines in Fig. 18, so as to eject the bale-wire which is moved quickly along the angular inner edge of the ejector toward one side of the machine. As soon as the ejecting action has taken place, the ejector is returned with the latch 15 by the action of a helical'spring 6 between the ejectorarms into its former position, as shown in full-lines in Fig. 16, and is arrested by a stop-shoulder.25 of its guide-strip 25 attached to the upper front-edge of the stand ard A The reciprocating slide-pieces 1g are engaged and actuated by the slidingsleevesBfB on the shafts C, C of the crossheadand eye-bending devices, as shown in Fig. 3, so as to move forward with the sliding-sleeves during the bending operation for operating the wire-clamping de-,

vices and return with the sliding-sleeves after the shank-twisting operation is completed for actuating the ejecting devices.

From the upper corners of the upright standard A extend in downward direction at both ends of the standard curved guidebands which are bent inwardly at their lower ends and attached to the frame A of, the machine, asshown clearly in Figs. 1, 2 and 16. fi-The curved bands 1' serve as guides for the completed wire bale-ties when they are thrown off at opposite sides of the machine by the ejecting devices.

0peratz'on.The operation of my improved machine for bending the crossheads and eyes of wire bale-ties is as follows:

After inserting the wireblank a into proper position through the guide-devices and eyes of the ejecting devices into the crosshead or eye-bending devices, and placing the power-belt on the pully P, the hand-lever H is operated so that the clutch-member n on thereby the end of the wire-blank a into the shape of the crosshead, as shown in Fig. 31, and described in connection with the crosshead bendingdevices. As soon as the bending-operation is completed, the shank of the crosshead is firmly taken hold of by the clamping-devices, ready for the operation of the shank-twisting mechanism. The bending of the end of the wire-blank into the form of a crosshead, the clamping of the shank of the same and the twisting of the shank are so timid as to take place in proper succession by the motion of the reciprocating slide-plate Q on the shifting-lever L and heads L and on the clamping-devices and shank-twisting mechanisms described. On the return of the reciprocating slideplate Q and the bending-devices into their initial or starting positions, the crosshead formed at the end of the wire bale-tie is released from the bending-devices by the spring actuated and laterally movable pusher and subjected to the action of the ejector which throws the bale-tie, with the crosshead formed thereon, quickly sidewise out of the machine. Simultaneously with the return of the shifting-sleeve B and diehead E into their former position, the power-shifting mechanism is operated and the lever L shifted in the manner before described, so that the power is shifted by the shiftable heads L from the shaft C of the crosshead-bending devices to the shaft C of the eye-bending devices, the shaft C remaining in a position of rest. By the next forward motion of the reciprocating slide-plate Q, the shifting-sleeve B on the shaft C is moved in forward direction so as to act on a second wire-blank, inserted into the eye-bending devices, and bend its end into the form of the eye, shown in Fig. 35, which is then clamped, its shank twisted and the wire ejected at the opposite side of the machine, in the same manner as the bale-wire with the crosshead formed thereon. The return-motion of the slide-plate produces again the operation of the power-shifting mechanism so as to place the shifting-lever L and laterally-shifting heads L into engagement wit-h the sliding-sleeve B on the shaft C, and produce by the next forward motion of the slide-plate Q the actuation of the crosshead-bending, wire-clamping and shank-twisting devices, and so on alternately the formation of crossheads or eyes at the ends of the wire-blanks and their ejection by the ejecting devices at opposite sides of the machine.

The machine hereinbefore described is arranged with crosshead and eye-bending devices which are alternately operated by the automatically operated power shifting mechanism. In place of the die-heads forming the crossheads and eyes shown, other dicheads with modified bending-devices may be attached to the shafts C, C of the bendingdevices, so as to permit the use of the machine for the bending of arrow or other shaped crossheads and differently-shaped loops for the same.

The improved machine herein described for bending crossheads and eyes of wire baletires has the advantage that by the great simplification of the power-shifting mechanism the number of operative parts is greatly diminished and the automatic shifting of the power from the shaft of the crosshead bending-devices to the shaft of the eye-bending devices, after the machine is started, simplified to such an extent that a very large number of wire bale-tires can be completed within a given time by only one attendant for feeding the wire-blanks alternately to the bending-devices. Owing to the improved construction of the machine it is less liable to injury and breakage so that the frequent repairs heretofore necessary with this type of machine are to a great extent obviated while such repairs as become necessary can be made by the substitution of interchangeable reserve-parts without returning the machine for repairs to the place of manufacture.
